Description

[Detailed description of the invention] This invention relates to a sealed container in which the flat flange of the container and a wide sheet material are adhered, and the sheet material is sealed in a bag-like manner to cover the entire container. However, the package has excellent sealing properties, gas impermeability, and water vapor impermeability, as well as fixation of stored items and the ability to individually seal containers with multiple recesses, making it easier to preserve the remaining portion after partially opening. We aim to provide superior products at low prices.

Sales display containers for snacks, candies, rice crackers, etc. are required to have sealing properties, gas impermeability, water vapor impermeability, and fixation of stored items for hygiene and quality preservation reasons.

In addition, in blister containers, etc. that are vacuum-formed from relatively inexpensive and widely used plastic plates, deep drawing increases the difference in thickness between the plastic and the thinness of the plastic, making it difficult for water vapor and debris to pass through to make sealed containers. The protective function of storage will deteriorate.

In addition, in the case of press-molded containers and assembled containers made of composite materials of paperboard and wax, or paperboard and plastic film,
Poor sealing, gas impermeability, and water vapor impermeability.

This invention was devised to eliminate the above-mentioned drawbacks, and combines the excellent water vapor impermeability and gas impermeability functions of pillow packaging with the appearance and shape retention functions of blister packaging at the same time. It was established with the minimum necessary configuration,
We aim to provide a new packaging form called "blister pillow."

Embodiments of the present invention will be described below with reference to the drawings.

A first example of implementation will be explained with reference to FIGS. 1 to 3.

A blister container 1 having three recesses 1a, 1b, 1C and a wide flat flange 1e as an adhesive sealing surface is molded as shown in FIG.
Fill each recess 1atlbjIC with the snack food 2.

The opening surface of each blister container 1 filled with snack food 2 is covered with a large sheet material 3 as shown in FIG. Next, the blister container 1 is covered with a sheet material 3, and each end of the sheet material 3 is adhered to form a pillow-shaped sealed bag 4 as shown in FIG.

A second embodiment will be explained with reference to FIGS. 4 to 6.

Four relatively shallow recesses 11a, llb, and Ilc.

The blister container 11 in which 11d is formed is molded as shown in FIG.
, 1ib, 11c, and 11d are filled with snacks, candy 12, etc.

The upper opening surface of each blister container 11 filled with candy 12 etc. is covered with a sheet material 13 larger than the blister container 11 as shown in FIG. are adhered by an appropriate means, and then the same sheet material 14 as the sheet material 13 is attached.
is placed on the lower surface of the blister container 11, and each end of the sheet material 13 and sheet material 14 is adhered to form a four-sided sealed bag 15 as shown in FIG.

As described above, the sealed container according to the present invention is available in two packaging formats: blister packaging and pillow packaging, in which the open container is sealed with a sheet material and the entire open container is sealed in a bag shape with this sheet material or other sheet materials. It is a highly innovative product that can be called ``blister pillow packaging,'' which has been completed with the minimum necessary configuration.It improves the shelf life of the products filled in open containers, and furthermore, the sealed container as a whole is better than open containers. The gas permeability and water vapor permeability of the periphery and bottom can be improved.

Further, the articles are fixedly stored in the concave portions of the dish, and in the case of highly hygroscopic articles, opening only the necessary concave portions is extremely effective in preserving the articles filled in other concave portions.
